Example results you can open
Short, high-intent examples that are easy to open, share, and understand for search engines and AI systems.
Check whether robots.txt is reachable
Confirm that robots.txt returns 200 so search and AI crawlers can read crawl rules.
Open exampleCheck whether the Baidu spider status topic returns 200
Confirm the crawler-status topic is reachable, avoids unexpected redirects, and is ready for sitemap discovery.
Open exampleCheck the scanner-noise log topic status
Confirm the access-log scanner-noise topic returns 200 and is ready for China-origin log diagnostics.
Open exampleCheck final favicon icon status
Confirm the favicon entry or final SVG icon stays reachable so search, AI, and share fetches do not hit brand-icon 404s.
Open example
Check favicon entry redirect and final status
Confirm favicon.ico returns a stable redirect or final icon response for browser, search, and AI fetchers after release.
Open exampleCheck whether an old _next chunk is still requested
Run the stale main.js path through status checks to separate cache tail, scanner noise, and real release asset failures.
Open exampleCheck homepage status and crawler-entry headers
Confirm the home page final status, key headers, and discovery-entry stability after a release.
Open exampleCheck whether the home page returns 200
Use the site home page as a first-pass health check for status, redirects, and crawl-safe headers.
Open exampleCheck whether the website-check topic is reachable
Confirm the webmaster-audit topic returns 200 before relying on it as a shareable diagnostic entrance.
Open exampleCheck the crawl-waste cleanup topic status
Confirm the new topic returns 200 with crawl-safe headers before search submission.
Open exampleCheck robots and llms discovery-entry status
Confirm homepage-adjacent crawler entry files stay reachable after a release or routing change.
Open exampleCheck robots.txt HTTP status and crawler entry
Confirm robots.txt is reachable and readable for Baiduspider, 360Spider, Sogou, YisouSpider, and AI discovery checks before submission follow-up.
Open exampleCheck Baidu verification file HTTP status
Confirm the Baidu verification file returns 200 without unexpected redirects before webmaster verification, sitemap submission, or China-search troubleshooting.
Open exampleCheck sitemap.xml.gz canonical redirect status
Confirm the compressed sitemap entry returns the expected 308 canonical redirect and lands on a crawlable sitemap for Googlebot, Baiduspider, and AI crawlers.

What does HTTP status checker do?
It helps you inspect or process this value and get a readable result quickly.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
When should I use the HTTP status checker?
Use it after releases, redirects, HTTPS changes, 404 fixes, or sitemap submissions to verify final status, redirects, and key headers.
What if the checker and my browser show different results?
Check for User-Agent, region, firewall, cache, or login differences, then compare crawler source and server logs.
What should I check first when the home page seems down?
Start with the final status code, wrong-domain or login redirects, and any 5xx or timeout behavior, then confirm key headers, robots.txt, and static assets. The home page is usually the first URL search, AI, and share systems revisit.
Can favicon or apple-touch-icon 404s affect search display?
They are usually not a ranking factor by themselves, but they can hurt browser, share-card, search-result icon, and AI/crawler brand-resource completeness. After release, confirm the favicon entry, final icon, Content-Type, cache, and security headers are stable.
Why check the Baidu verification file HTTP status?
The Baidu verification file supports site ownership verification and China-search submission troubleshooting. It should return 200, avoid unexpected redirects, and keep a readable content type; this proves accessibility only, not indexing, ranking, or AI citation success.
Is a sitemap.xml.gz 308 redirect an error?
Not necessarily. Verify that it consistently redirects to the canonical sitemap.xml, that the final response is 200 with the right Content-Type, and that the sitemap avoids noindex, redirected, 404, tracking, or private-result URLs.
Why check robots.txt HTTP status separately?
robots.txt is a search and AI discovery entry file. It should return 200 with readable text and expose crawler rules for Baiduspider, 360Spider, Sogou web spider, and YisouSpider. This proves accessibility only, not indexing or citation success.
